[PyGame] ROLL function

[Zman350x]

I am making a dice game, here is my roll function.
What I want to happen is for the loop to repeat 9 times(or 10 I can't tell) and each time pick a different dice side to blit to mimic rolling the die. Instead, whats happening is it generates a random side on both die like it should and then only blits it the last time.

def ROLL():
        rolltime = 1                      #rolltime is a variable that goes up by one each time it loops
        while True:
            if rolltime <= 10:      
                DiceRoller1 = random.choice(Dice)    #Dice is a list of 6 images, one of each side
                DiceRoller2 = random.choice(Dice)    # in the game there are two dice you roll
                screen.blit(DiceRoller1,(0,0))             #this and the next line are whats giving me issues
                screen.blit(DiceRoller2,(75,0))
                rolltime += 1
                clock.tick(10)
                for event in pygame.event.get():
                    if event.type == pygame.QUIT:
                        pygame.quit()
                        quit()
            else:                           #if rolltime is over ten the loop breaks
                break
